Lance's P.O.V.
I'm scrolling through my Instagram eyeing Shiro and his obvious nervousness. He's trying pretend he's reading but I can tell he's not even paying attention to what's on the page. He's been nervous and stressed all day but he insists nothing is wrong.

I'm starting to get really worried about him. He only acts like this after he has nightmares or he's really stressed at work. I really should confront him about this again, there's no chance of solving it if I don't know what's going on.

"Shiro, come here." I say and he looks over to me, walking over and sitting down

I wrap my arms around him and press a kiss to his cheek.

"You know you can come talk to me whenever you want right?" I ask "I'm here for you."

"I know." He replies, looking down nervously

"So why don't you tell me what's going on?" I question "Obviously something is wrong and I want to help."

"I just don't know how you'd react." Shiro sighs

"I won't judge you." I state, smiling softly

"Well ok, what if I told you I wanted to role play?" Shiro says and my breath catches in my throat

"Role play?" I ask confused

"I've read about people role playing during sex." He explains "It sounds like a lot of fun."

"So what type of role play did you have in mind?" I ask "Student and teacher? Daddy and sugar baby?"

"Master and slave." He says catching me off guard

"Why master and slave?" I ask

"What If I said I wanted complete control over you?" Shiro asks, turning towards me "That I want to tell you what to do and how to act. That the situation could be completely out of your hands if you wanted, that all you'd need to focus on is the pleasure you feel."

"Well that sounds pretty hot." I say "I'd say yes."

"Well then, when do you want it?" Shiro asks

"What about right now? All that talk made me especially horny." I answer

Shiro smiles and picks me up, I wrap my legs around his waist and he carries me with ease. We press out lips together in a passionate kiss and Shiro's carries me to the bedroom. Once inside he places me on the bed and pulls away.

"We need to talk about this." Shiro says "Like safewords and stuff."

"Ok, want to go with the basic ones?" I ask "Like red for stop, green for go and yellow for slow down?"

"They seem the easiest to remember." Shiro agrees

I crawl into his lap, pressing a kiss to his lips, not expecting to be pushed off and land on the floor. I didn't hurt myself but I look up in shock.

"Did you think you could just kiss me slave?" Shiro asks

"Shiro?" I ask shocked

He grabs my chin and forces me to look at him, he's holding tightly but not enough to hurt me.

"Call me master." He growls

I sit up a little straighter and look into his eyes.

"Sorry master~" I say and Shiro smirks

"That's more like it." Shiro says "You're my slave."

"Only your's master." I giggle

"Well how about you show me?" He asks

I look down to the huge tent forming in his pants and gingerly unzip his pants, pulling down his boxers. His huge erection springs out and I start to feel a little nervous.

"Don't keep me waiting slave." Shiro growls and I move so I can take his tip into my mouth

I open my mouth and take in his throbbing red tip. I suck softly on it and Shiro's hand goes to the back of my head, quickly pushing me down, forcing me to take in more. I yelp slightly but continue to push my head down further. I hollow out my cheeks and suck harder on Shiro, bobbing my head up and down.

His soft moans and groans give me confidence and I continue to suck him off. After a few minutes I feel him twitch and with a loud moan he cums into my mouth.

"Swallow it all." He says as I pull off of his dick

I swallow it but a little dribbles out of the corner of my mouth.

"You spilt it." Shiro says, wiping it away harshly

"You just came too much!" I defend myself

"Silence slave, I think you need some punishment." Shiro smirks "I can't have a disobedient slave."

I get more excited at his words and my pants become very tight. What's he going to do? Spank me? Leave me on the edge? Be extra rough? I'm ready for anything. I'm really starting to like this role play thing. I love seeing Shiro being this dominant.

Shiro pulls me up so I'm bent over his lap, he pulls down my pants and boxers revealing my bare ass.

"What are you going to do master?" I ask

"I think you know." He replies

Suddenly I feel a sharp pain on my ass and I cry out.

"Does that hurt slave?" Shiro asks, stroking my ass cheek and then slapping it again

It hurts but it strangely feels good as well. Shiro repeats this action, only using his human hand. I don't know if I'd be able to handle the metal one. After about nine slaps Shiro rubs my bright red cheeks softly.

"Learnt your lesson?" Shiro asks

"Yes master." I reply, panting

"Now how about I see if this cute little hole will do a better job at swallowing my cum than your mouth?" Shiro says, rubbing his thumb over my hole

"Ahh Master~" I moan as he pulls open my hole with his thumb

"How cute, this is how I like you slave." He says "On my lap, moaning my name. Now I'll make you beg, but first strip."

I pull off my pants and boxers fully before taking off my shirt. Shiro removes his clothes as well. He moves me so I'm on my back on the bed and he's above me. Butterflies fly around in my stomach and Shiro lines up with my entrance.

"You haven't stretched me master." I say

"I don't think you need it." He smirks

He pushes a little into me and it feels a little painful but also good. I try to move my hips to take more of him in but he moves with me keeping his tip in the same spot.

"Please master~" I beg and he pushes in a little more

"Who do you belong to?" Shiro whispers in my ear "Answer and I'll give you what you want."

"You master!" I beg "Please~"

"Not very convincing slave." Shiro chuckles

"I belong to master Shiro!~" I moan "Only you master, more please~"

He suddenly snaps his hips in the full way and I scream in pain and pleasure. I feel so full and he's stretching me so wide, but the pain doesn't seem to be fading away fast enough.

Shiro starts thrusting slowly, I think he's trying to make sure I'm ok from his sudden movement. I try to focus on the pleasure but the pain isn't going away. I don't know, I should still be stretched from yesterday.

"Ahh red!" I call out and Shiro stops immediately

"Lance are you ok?" Shiro asks worried

"I think so, I just need a moment." I say resting my head on his shoulder

Shiro nods and presses a kiss to my forehead, whispering about how I'm a good boy and I'm doing perfectly.

"I'm ok now." I say, smiling softly "I think I was just a bit worked up."

"Are you sure?" Shiro asks and I nod "Ok, if you need to stop again then tell me ok?"

"I will." I say "Master~"

At that Shiro seems to snap back into his dominant mind set and push into me again, slower to make sure he doesn't hurt me but still rough. I roll my hips to feel it more and I moan loudly.

"Ahh master~" I cry out and Shiro picks up speed and power

His roughly moves me around so I'm on all fours in the crouch while he is pounding into me from behind. He moves his metal hand to my weeping member and his hand behind to vibrate.

"Ahh~!" I scream in pleasure

Shiro moves faster, I know I'm going to have bruises tomorrow.

"Who do you belong to slave?" Shiro grunts

"Ahh you master~" I moan, tears of pleasure building in my eyes

"Don't cum before me slave." He says, his metal arm vibrating harder

I try to hold off from cumming which is very hard to do with everything Shiro is doing to me. Finally I feel a burst of heat inside me as Shiro cums inside. I cum a few seconds after into Shiro's hand.

Shiro pulls out gently but keeps me pushed down so nothing spills out.

"Don't spill any." Shiro says

"But I need to get up~" I whine

"Wait here." He replies, getting off the bed and walking away

He comes back a second later with a black object. He presses it to my opening and it slides in perfectly. I groan as it enters me and then Shiro pulls me so he's carrying me bridal style. It must be a butt plug inside me.

"Are you ok?" Shiro asks

"Mm-hm." I nod

"I think we should shower then go to sleep." He says

"Sounds good." I giggle

He takes me to the bathroom and runs a bath for both of us. Shiro is really good at taking care of me and making sure I'm ok. He washes me off and checks if I'm ok again, giving me lots of praise, hugs and kisses. I would definitely do this again.
